Description

The HIP0060 is a 5V logic controlled Quad Low Side Power

Driver. The outputs are individually protected for over-current

(OC), over-temperature (OT) and over-voltage (OV). If an OC

power driver, that output current will be independently limited

while the other outputs remain in operation. Over-current is

limited by direct gate feedback. Over-voltage protection is pro-

vided by a drain-to-gate zener diode that clamps inductive

switching pulses.

The output drivers are individually controlled through a Gate

Control Latch. Temperature is sensed at each output. If a ther-

mal fault exists, a status flag is set and the output is latched

off. Open-load (OL) and over-temperature (OT) faults sets a

status flag bit as diagnostic output to the SPI bus. For all fault

bits (8), an ORed one-shot interrupt signal is output to the INT

pin. An RST reset clears the fault flags and disables all out-

puts while active. The Serial Peripheral Interface (SPI) bus

pins are the Serial Input (SI), Serial Output (SO), Serial Data

Clock (SCK) and the Chip Select (CS).

The HIP0060 is fabricated in a Power BiMOS IC process, and

is intended for use in automotive and other applications having

a wide range of temperature and electrical stress conditions. It

is particularly suited for driving lamps, relays, and solenoids in

applications where low operating power, high breakdown volt-

age, and higher output current at high temperatures is required.
